IHPCL and Systems ResearchCluster and Machine Benchmarking

HPC and interactive applications (Neil Bright, Matt Wolf, others)

DEOS Project - intra-clusters and `periphery’ with Yamacraw effort (Karsten Schwan)

Dynamic kernel extension (Linux) - `pushing code’ into kernels Adaptable wireless communications (Java- and C-based)

ASAN Project (Active System Area Networks) with ECE and Critical Systems Lab (Ken Mackenzie)

`Pushing’ code into the network Working with NICs and programmable routers

Research Problems/Solutions

Multiple information providers, transformers, consumers (e.g., consider large wireless systems)

Continuous Service Delivery despite changes in resources (e.g., consider wireless)Client-specific service delivery (e.g., PDAs vs. laptops, Java vs. C, Linux vs. PalmOS)

Dynamic client behavior (e.g., runtime interest changes)Real-time performance

Support publish/subscribe paradigm with flexible service location: ECho, JECho, dyn. filters

Offer continuously `useful’ services through client-specific dynamic service adaptationDifferentiate among clients at connection establishment; offer multi- and cross-platform support (e.g., XML)Continuously update client `profiles’ (i.e., ‘dynamic portals’)Runtime configuration of open source system: e.g., use ECalls and K-ECho to monitor available resources and current needs.

• Middleware: • ECho, JECho: online channel control (e.g., client-based control, inline filtering) and monitoring• Proactive Directory Services

• ELinux: • Runtime OS extension for open platforms• ECalls and K-ECho• QoS-aware packet and task scheduling using DWCS

• QSockets• Application-specific channel bonding

• Extensible cluster-wide /proc•ASAN Project - next

Composition and Platform Extension

Major advances in computing systems in the next decade and beyond will arise from integration of technologies to solve new problems and generate new capabilities.

The role of the center is to promote such synergy via capabilities for experimentation.

The center provides the infrastructure to support experimental efforts in the design of the future generations of computing systems and software.
